Begonia plant named ‘BKPBEWFASO’

ABSTRACT

A new and distinct cultivar of  Begonia  plant named ‘BKPBEWFASO’, characterized by its upright to broadly outwardly spreading and eventually hanging plant habit; freely branching habit; dark green-colored leaves; freely flowering habit and long flowering period; large salmon and light yellowish pink-colored flowers; and good garden performance.

Botanical designation: Begonia pendula.

Cultivar denomination: ‘BKPBEWFASO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia pendula and hereinafter referred to by the name ‘BKPBEWFASO’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program was to develop new freely flowering Begonia plants with large attractive flowers and good garden performance.

The new Begonia plant originated from a cross-pollination made by the Inventor in January, 2011 of a proprietary selection of Begonia pendula identified as code number 03-H28, not patented, as the female, or seed, parent with a proprietary selection of Begonia pendula identified as code number 10-000-29, not patented, as the male, or pollen, parent. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in July, 2011.

Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since August, 2012 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BKPBEWFASO’. These characteristics in combination distinguish ‘BKPBEWFASO’ as a new and distinct Begonia plant:

-   -   1. Upright to broadly outwardly spreading and eventually hanging         plant habit.     -   2. Freely branching habit.     -   3. Dark green-colored leaves.     -   4. Freely flowering habit and long flowering period.     -   5. Large salmon and light yellowish pink-colored flowers.     -   6. Good garden performance.

Plants of the new Begonia can be compared to plants of the female parent selection. Plants of the new Begonia differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Begonia have single and semi-double flowers         whereas plants of the female parent selection have double         flowers.     -   2. Plants of the new Begonia have salmon and light yellowish         pink-colored flowers whereas plants of the female parent         selection have bright orange-colored flowers.

Plants of the new Begonia can be compared to plants of the male parent selection. Plants of the new Begonia differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Begonia are not as compact as plants of the         male parent selection.     -   2. Plants of the new Begonia have larger flowers than plants of         the male parent selection.     -   3. Plants of the new Begonia have salmon and light yellowish         pink-colored flowers whereas plants of the male parent selection         have pink and white-colored flowers.

Plants of the new Begonia can be compared to plants of the Begonia pendula ‘BKBEWFAFSP’, disclosed in U.S. Plant Pat. No. 24,304. In side-by-side comparisons conducted in Maasdijk, The Netherlands, plants of the new Begonia differ from plants of ‘BKBEWFAFSP’ in the following characteristics:

-   -   1. Plants of the new Begonia have slightly larger flowers than         plants of ‘BKBEWFAFSP’.     -   2. Plants of the new Begonia have salmon and light yellowish         pink-colored flowers whereas plants of ‘BKBEWFAFSP’ have light         and dark pink-colored flowers.

Plants of the new Begonia can also be compared to plants of the Begonia ‘Dainty Dancer Apricot’, not patented. In side-by-side comparisons conducted in Maasdijk, The Netherlands, plants of the new Begonia differ from plants of ‘Dainty Dancer Apricot’ in the following characteristics:

-   -   1. Plants of the new Begonia are not as freely branching as         plants of ‘Dainty Dancer Apricot’.     -   2. Plants of the new Begonia have larger flowers than plants of         ‘Dainty Dancer Apricot’.     -   3. Plants of the new Begonia have salmon and light yellowish         pink-colored flowers whereas plants of ‘Dainty Dancer Apricot’         have apricot-colored flowers.
